This can be achieved, from one hand, by decreasing the mixing and laying temperatures of asphalt mixtures.
The study aimed to verify and to assess, though an analytical-sensory approach based on artificial olfactory system (AOS), the effects of five different asphalt additives (chemical additives, odor suppressant agent and wax modifiers) on the odorous patterns of asphalt emissions at typical mixing and laying temperatures.
In the present work, oxide scale formed on low carbon steel during conventional wire rod rolling (∼ 1.4 °C s− 1 cooling rate after laying head temperature, LHT, at 900 °C) was investigated.
The observed population trend (i.e. βB) as function of breeder density – without a significant within-individual component – and the observation of steeper laying date spring temperature slope with increasing breeder density in the environmental determinant analysis suggested that females living on average at lower densities were possibly constrained in their plastic response.
Data that would be informative in modeling establishment success in the field include such factors as optimum egg-laying temperature, temperature required for flight, and population growth rates at three or more temperatures.
Immediately after cold exposure each group of 20 flies was transferred back to a room temperature laying vial and returned to the controlled temperature room at 25°C.
Warm Mix Asphalt (WMA) technologies allow reducing production, laying and compaction temperatures of bituminous mixtures, leading to relevant environmental and technical benefits.
It has been shown that, compared to animals not exposed to high ambient temperatures, laying hens that are exposed to cyclic heat stress have decreased T-cell and B-cell proliferations and antibody titre to sheep red blood cells and an increased total white blood cell count [ 71], which supports the hypothesis that the immune function is disrupted during heat stress.
The main process parameters investigated were the compaction force, tape laying speed and tool temperature.
It is particularly noteworthy that not all individuals responded to changes in temperature; individuals laying few eggs at 20°C continued to do so when transferred to 12°C, whereas individuals that laid many eggs at 20°C reduced their oviposition and laid the same number of eggs as the others when transferred to 12°C.
The function f(ID x,i, TEMP) allows among-individual variance around the population fixed-effect mean change in laying day over spring temperature.
